HAND-POWER.

SPECIFICATION forming part of Letters Patent No. 232,244, datedSeptember 14, 1880.

Application filed May 17, 1880. (Model) To all whom it may concern Be itknown that I, ROBERT P. DAKE, of Colby, in the county of Marathon andState of Wisconsin, have invented a new and useful Improvement inHand-Powers, of which the following is a specification.

Figure 1 is a plan view of the improvement. Fig. 2 is a side elevation.

Similar letters of reference indicate correspondin g parts.

The object of this invention is to furnish hand-powers for driving lightmachinery, such as straw-cutters, pumps, churns, grindstones,sawing-machines, lathes, boats,'and other light machines where otherpower is not attainable, and which shall be simple in construction andconvenient in use.

The invention consists in constructing a hand-power of one or more pairsof levers and their connecting-rods, the shaft having a crank at eachend, the gear-wheels, and the shaft having a pulley and crank, both oreither, whereby motion can be given-to machinery by hand-power, as willbe hereinafter fully described.

A represents the frame of the handpower, which consists of twolongitudinal bars connected at their ends by cross-bars.

B are two levers, the lower ends of which are pivoted to supportsattached to the lower parts of the outer sides of the side bars of theframe A. The levers B pass through keepers 0, attached to the upperparts of the outer sides of the side bars of the frame A.

To the levers B, a little above the frame A, are pivoted the ends ofconnecting-rods D, the forward ends of which are pivoted to the cranksE, attached to the ends of the shaft F. The cranks E project in oppositedirections, or at an angle with each other, so that they will not bothbe upon the dead-point at the same time.

The'shaft F revolves in bearings attached to the frame A, and to itsmiddle part is attached a gear-wheel, G, the teeth of which mesh into asmaller gear-wheel, H, attached to the middle part of the shaft I. Theshaft I is placed parallel with the shaft F and revolves in hearingsattached to the frame A.

To one end of the shaft I is attached a pulley, J, to receive a belt fordriving any desired machinery constructed to be driven by a belt. To theother end of the shaft I is attached a crank, K, to be connected withany desired machinery constructed to be driven by a crank motion.

To the levers B are pivoted the forward ends of the connecting-rods D,the other ends of which are pivoted to a second pair of levers, B. Thelevers B pass through keepers 0, attached to the frame A.

The lower ends of the levers B are pivoted to supports attached to theouter sides of the side bars of the frame A in such positions that thelevers B will be parallel with the levers B.

The frame Ais designed to be covered with a floor or platform for theman or men operating the levers to stand upon, or to support a seat whenthe operatorwishes to sit at his work.

The second pair of levers is designed for use when the machinery to bedriven is too heavy to be driven by the strength of a single man.

When the hand-power is to be used for propelling a boat the paddle-wheelmay be attached to the shaft F, or may be connected with the shaft I, asmay be desired or convenient.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent- 1. A hand-power constructed substantially as hereinshown and described, consisting of one or more pairs of levers, B, andconnecting-rods D, the cranks E, the shafts F I, the gear-wheels G H,and the pulley and crank J K, both or either, as set forth.

2. In a hand-power, the combination, with the driving-shaft I, havingpulley J and crank K, both or either, of the gear-wheels H G, the shaftF, haviu g cranks E, the connecting-rods D, and the levers B,substantially as herein shown and described, whereby motion can be givento the driving-shaft by hand-power, as set forth.

3. In a hand-power, the combination, with the shaft I, having pulleyJand crank K, both or either, the gear-wheels H G, the shaft F, havingcranks E, the connecting-rods D, and the levers B, of a second pair ofconnectingrods, 1), and levers B, substantially as herein shown anddescribed, whereby additional [0 power can be given to the machine, asset forth.
